6. WHAT ARE THE THREE GOALS OF WATER TREATMENT?

5. WHAT IS THE MAJOR DIFFERENCE BETWEEN DRINKING WATER TREATMENT AND WASTEWATER TREATMENT?

IN WASTEWATER TREATMENT YOU HAVE TO REMOVE MORE SOLIDS

6. WHAT ARE THE THREE GOALS OF WATER TREATMENT?

-REMOVE SOLIDS

-REMOVE CHEMICALS

-REMOVE MICROORGANISMS

7. WHAT IS THE FIRST STEP IN WATER TREATMENT?

8. WHAT IS FLOCCULATION?

7. WHAT IS THE FIRST STEP IN WATER TREATMENT?

THE REMOVAL OF LARGE SOLIDS

8. WHAT IS FLOCCULATION?

THE FORMATION OF A GELATENOUS PRECIPITATE TO REMOVE FINE SOLIDS AND MICROORGANISMS IN DRINKING WATER TREATMENT

9. AFTER WINSTON-SALEM TREATS ITS WASTEWATER, HOW CLEAN IS IT?

10. IN CURRENT WASTEWATER TREATMENT PROCESSES, CAN ALL TRACE CONTAMINANTS BE REMOVED?

9. AFTER WINSTON-SALEM TREATS ITS WASTEWATER, HOW CLEAN IS IT?

CLEANER THAN IT WAS TAKEN OUT OF THE YADKIN RIVER

10. IN CURRENT WASTEWATER TREATMENT PROCESSES, CAN ALL TRACE CONTAMINANTS BE REMOVED?

NO, MANY TRACE CONTAMINANTS ARE LEFT, SUCH AS DRUGS

11. BESIDES FLOCCULATION, WHAT STEP IN DRINKING WATER TREATMENT IS USED TO REMOVE RESIDUAL BACTERIAL AND VIRUSES?

CHLORINATION

12. WHAT OPTIONAL STEP TO PROTECT TOOTH ENAMEL IS DONE IN THE DRINKING WATER TREATMENT PROCESS?

FLUORIDATION

13. IN WASTEWATER TREATMENT, WHAT STEP IS DONE TO REMOVE DISSOLVED/SUSPENDED ORGANICS?

14. WHAT IS DONE WITH THE SLUDGE THAT IS REMOVED DURING THE WASTEWATER TREATMENT PROCESS?

13. IN WASTEWATER TREATMENT, WHAT STEP IS DONE TO REMOVE DISSOLVED/SUSPENDED ORGANICS?

AREATION

14. WHAT IS DONE WITH THE SLUDGE THAT IS REMOVED DURING THE WASTEWATER TREATMENT PROCESS?

IT IS SENT TO A DIGESTOR. PART IS CONVERTED TO METHANE, AND THE REMAINDER IS USED AS SOIL CONDITIONER

15. IF YOU LIVE IN A RURAL AREA, WHAT SHOULD YOU DO WITH YOUR WASTEWATER?

16. WHAT AGENCY REGULATES DRINKING WATER QUALITY?

15. IF YOU LIVE IN A RURAL AREA, WHAT SHOULD YOU DO WITH YOUR WASTEWATER?

SEND IT TO A SEPTIC TANK FOR PROCESSING

16. WHAT AGENCY REGULATES DRINKING WATER QUALITY?

EPA

17. WHAT AGENCY IS RESPONSIBLE FOR REGULATING BOTTLE WATER QUALITY?

18. WHAT IS YOUR FOURTH QUARTER PROJECT AND WHEN IS IT DUE?

17. WHAT AGENCY IS RESPONSIBLE FOR REGULATING BOTTLE WATER QUALITY?

FDA

18. WHAT IS YOUR FOURTH QUARTER PROJECT AND WHEN IS IT DUE?

MAY 16 – DESIGN A SUSTAINABLE COMMUNITY – WORK IN GROUPS OF 4

19. WHY WOULD YOU TEST FOR CONDUCTIVITY IN STREAMS?

20. WHAT IS TURBIDITY, AND WHY WOULD YOU TEST FOR IT IN STREAMS?

19. WHY WOULD YOU TEST FOR CONDUCTIVITY IN STREAMS?

HOW ELECTRICALLY CONDUCTIVE THE STREAM IS – IT IS A MEASURE OF DISSOLVED SALTS

20. WHAT IS TURBIDITY, AND WHY WOULD YOU TEST FOR IT IN STREAMS?

IT IS A MEASURE OF HOW CLOUDY A STREAM IS – IT IS A MEASURE OF SUSPENDED SOLIDS – TOO MUCH WOULD BE DETRIMENTAL TO AQUATIC ORGANISMS

21. WHAT IS EUTROPHICATION?

22. WHAT IS pH AND WHY WOULD YOU TEST FOR IT?

21. WHAT IS EUTROPHICATION?

IT IS A PROCESS THAT RESULTS IN DEPLETION OF DISSOLVED OXYGEN IN SURFACE WATER DUE TO EXCESSIVE GROWTH OF ALGAE CAUSED BY NUTRIENT BUILDUP

22. WHAT IS pH AND WHY WOULD YOU TEST FOR IT?

A MEASURE OF THE ACIDITY/BASICITY OF THE WATER. MUCH OUTSIDE THE RANGE OF 6 – 9 WILL RESULT IN DAMAGE TO AQUATIC ORGANISMS

23. WHAT IS A CLASS C STREAM?

24. WHY DO YOU TEST FOR E. COLI IN STREAMS?

23. WHAT IS A CLASS C STREAM?

A GENERAL USE STREAM – MOST STREAMS IN NORTH CAROLINA ARE CLASS C

24. WHY DO YOU TEST FOR E. COLI IN STREAMS?

IT IS A CHECK FOR ANIMAL WASTE IN THE STREAM
